Strategic knowledge sharing in Bayesian games

This paper provides a model for the study of direct, public and strategic knowledge sharing in Bayesian games. We propose an equilibrium concept which takes into account communication possibilities of exogenously certifiable statements and in which beliefs off the equilibrium path are explicitly deduced from consistent possibility correspondences, without making reference to perturbed games. Properties of such an equilibrium and of revised knowledge are examined. In particular, it is shown that our equilibrium is always a sequential equilibrium of the associated extensive form game with communication. Finally, sufficient conditions for the existence of perfectly revealing or non-revealing equilibria are characterized in some classes of games. Several examples and economic applications are investigated.     

Three New Real Estate Price Indices for Geneva,Switzerland

This paper develops constant-quality price indices for three categories of real estate-apartment buildings, vacant land, and condominiums—for the city of Geneva, Switzerland. We use both the hedonic and repeat sales models to estimate the price level and, in turn, the rate of price change. The general pattern of each series suggests that real estate prices in Geneva were fairly stable throughout the 1970s, increased sharply during the 1980s, but gave back some of these gains in the early 1990s. Interestingly, the sharp rise in prices in the second half of the 1980s is very similar to that found in some regions of the United States. We also consider the problem, implicit in the repeat sales method, of revisions in previously estimated price indices as additional data become available in later years.     

High-frequency credit spread information and macroeconomic forecast revision

We examine whether professional forecasters incorporate high-frequency information about credit conditions when revising their economic forecasts. Using a mixed data sampling regression approach, we find that daily credit spreads have significant predictive ability for monthly forecast revisions of output growth, at both the aggregate and individual forecast levels. The relationships are shown to be notably strong during ‘bad’ economic conditions, which suggests that forecasters anticipate more pronounced effects of credit tightening during economic downturns, indicating an amplification effect of financial developments on macroeconomic aggregates. The forecasts do not incorporate all financial information received in equal measures, implying the presence of information rigidities in the incorporation of credit spread information.

土地利用总体规划修编指标利益冲突问题研究

研究目的：分析规划修编中,中央和地方、地方和地方之间在确定规划指标时利益冲突的成因和表现形式。研究方法：文献资料法,博弈分析法。研究结果：中央政府和地方政府土地利用追求目标上的差异是导致规划指标分解过程中产生冲突的主要原因。政府之间信息不对称是造成指标分解冲突的重要原因。研究结论：整合中央和地方的利益、实行参与式规划,做好规划修编过程中的上下结合,减少冲突,使得各项指标的确定能够有利于协调区域发展,并得到各地区的认同。

《广告法 》上的"广告"——兼论《广告法》之修改和完善

以《广告法》上的"广告"为视点展开分析和论证,具有同时评判现行广告法制之各种制度设计的功能和价值。通过对《广告法》上的"广告"的诸要素的分析,以及对《广告法》所列举之违法商业广告的类型化梳理,有助于我们在深刻把握作为《广告法》规制对象的"广告"的真实内涵的基础上,全面评判《广告法》对"广告"之规制现状,进而为《广告法》的修改和完善提供参考与借鉴。     

商标法第三次修订的若干思考

商标法对保护市场经济的有序发展发挥着巨大作用,与人们的生活息息相关。现行商标法已不能满足商品经济的发展。修订商标法应保留相对理由审查制度,应加大对恶意行为人的处罚,驰名商标标准应增加商品质量优异和良好售后服务的内容。     

Does Greater Amount of Information Always Bolster Attitudinal Resistance?

Previous research suggests that attitudinal resistance to information that challenges a prior evaluation increases with the amount of information underlying the prior evaluation. We revisit this proposition in a context in which a set of important claims about a target brand are presented either alone—a lower amount of isolated information—or along with other favorable, but less important claims—a higher amount of embedded information. Results from two experiments show that when the challenge occurs immediately after the initial evaluation, a greater amount of embedded initial information does produce greater attitudinal resistance. However, when the challenge occurs after a delay, a lesser amount of isolated information produces greater attitudinal resistance. The findings qualify previous assumptions about the role of prior information in attitudinal resistance, and support a constructive view of judgment revision and attitudinal resistance.
